Quick Start

Basic Usage

from agentils import AgentsUtils
import os

# Set your API key
os.environ['GOOGLE_API_KEY'] = 'your-api-key-here'

# Simple text generation
@AgentsUtils.execute_llm(output="text")
def generate_story():
    return "Write a short story about a robot learning to paint."

story = generate_story()
print(story)

JSON Output

@AgentsUtils.execute_llm(output="json")
def analyze_sentiment():
    return """
    Analyze the sentiment of this text and return JSON with 'sentiment' and 'confidence':
    "I love this new AI assistant!"
    """

result = analyze_sentiment()
print(result)  # {'sentiment': 'positive', 'confidence': 0.95}

Function Calling with Tools

def get_weather(location: str) -> str:
    """Get the current weather for a location."""
    return f"The weather in {location} is sunny and 72°F"

@AgentsUtils.execute_llm_with_tools(
    tools=[get_weather],  # Pass Python functions directly!
    automatic_function_calling=True
)
def weather_assistant():
    return "What's the weather like in San Francisco?"

response = weather_assistant()
print(response)

Advanced Configuration

@AgentsUtils.execute_llm_with_tools(
    model_name="gemini-2.0-flash-001",
    temperature=0.7,
    max_output_tokens=1000,
    system_instruction="You are a helpful coding assistant",
    tools=[get_weather],
    output="json"
)
def advanced_task():
    return "Help me plan a coding project with weather considerations"

Chat Sessions

# Create a chat session for multi-turn conversations
chat = AgentsUtils.create_chat_session(
    system_instruction="You are a helpful assistant",
    tools=[get_weather]
)

response1 = chat.send_message("Hello!")
response2 = chat.send_message("What's the weather in Tokyo?")

Utility Functions

from agentils import Utils

# JSON operations
data = Utils.string_to_dict('{"key": "value"}')
json_str = Utils.dict_to_string({"key": "value"})

# File operations
Utils.save_dict_to_file(data, "data.json")
loaded_data = Utils.load_dict_from_file("data.json")
